Introduction
An Enquiry into the Obligations of Christians (1792)
Context: As our blessed Lord has required us to pray that his kingdom may come, and his will be done on earth as it is in heaven, it becomes us not only to express our desires of that event by words, but to use every lawful method to spread the knowledge of his name. In order to this, it is necessary that we should become, in some measure acquainted with the religious state of the world; and as this is an object we should be prompted to pursue, not only by the gospel of our Redeemer, but even by the feelings of humanity, so an inclination to conscientious activity therein would form one of the strongest proofs that we are the subjects of grace, and partakers of that spirit of universal benevolence and genuine philanthropy, which appear so eminent in the character of God himself.

General sources
Context: It has in all ages been allowed that the communion of saints extends to those in paradise as well as those upon earth as they are all one body united under one Head. And "Can death’s interposing tide / Spirits one in Christ divide?" But it is difficult to say either what kind or what degree of union may be between them. It is not improbable their fellowship with us is far more sensible than ours with them. Suppose any of them are present, they are hid from our eyes, but we are not hid from their sight. They no doubt clearly discern all our words and actions, if not all our thoughts too; for it is hard to think these walls of flesh and blood can intercept the view of an angelic being. But we have in general only a faint and indistinct perception of their presence, unless in some peculiar instances, where it may answer some gracious ends of Divine Providence. Then it may please God to permit that they should be perceptible, either by some of our outward senses or by an internal sense for which human language has not any name. But I suppose this is not a common blessing. I have known but few instances of it. To keep up constant and close communion with God is the most likely means to obtain this also.
